Second solution
Edited again, so most multicite commands work.
Edited so \footcite now works.
A reasonably effective solution that preserves many of biblatex's featuers is provided by adjusting the way the year gets printed in citations. This can be done by redifining the commands associated to cite:year and cite:extrayear. This has the advantage of preserving the ibidem feature.
The code below includes a sample bibliography and then the main file with the redefined citation code.
\begin{filecontents}{test.bib}
@Article{Test,
author = {Author, A. N.},
title = {Article title},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test2,
author = {Author, A. N.},
title = {Second article},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test3,
author = {Author, A. B.},
title = {Third article},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test4,
author = {Author, A. N.},
title = {Fourth article},
year = 2007,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
\end{filecontents}
\documentclass{article}
\usepackage[style=authoryear-icomp,autocite=plain]{biblatex}
\addbibresource{test.bib}
\renewbibmacro*{cite:labelyear+extrayear}{%
\iffieldundef{labelyear}
{}
{\iftoggle{blx@footnote}
{\printtext[bibhyperref]{%
\printfield{labelyear}%
\printfield{extrayear}}}
{\footnote{\printtext[bibhyperref]{%
\printfield{labelyear}%
\printfield{extrayear}}}}}}
\renewbibmacro*{cite:extrayear}{%
\iffieldundef{extrayear}
{}
{\iftoggle{blx@footnote}
{\printtext[bibhyperref]{\printfield{extrayear}}}%
{\footnote{\printtext[bibhyperref]{%
\printfield{labelyear}%
\printfield{extrayear}}}}}}
\renewcommand{\compcitedelim}{\space}
\begin{document}
\thispagestyle{empty}
\autocite{Test} and
\autocite[page 3]{Test}.
Some text \parencite{Test2}.
Here is a footnote citation\footcite{Test}.
\autocite{Test,Test4,Test3}.
\printbibliography
\end{document}
As the above shows this works with \autocite, \parencite and accepts their optional arguments. In this style \autocite is the same as \cite.
I haven't demonstrated \textcite, though its ouptut may be useful sometimes; \footcite has also been set up to work, thanks to biblatex's blx@footnote toggle that detects whether we are in a footnote or not.
The code also takes care of most multiple citations \cite{ref1,ref2}. However, there is a spurious comma, if ref1 and ref2 are two publications from the same author in the same year. Fixing that requires, more substanitial rewriting of the citation style file: each of the commands \cite, \textcite, etc. in author-icomp.cbx contains an explicit comma via \setunit{\addcomma}, that needs to be deleted.
Original solution
Here is a repost of the original solution, as this apparently helps the OP best. It simply defines a newcommand \citepfy (plain-foot-year) that calls \citeauthor followed by a modified \footcite command that produces only the year. It does not accept any of the optional arguments cite commands in biblatex usually do.
\begin{filecontents}{b.bib}
@Article{Test,
author = {Author, A. N.},
title = {Article title},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
\end{filecontents}
\documentclass{article}
\usepackage[style=authoryear-icomp]{biblatex}
\addbibresource{b.bib}
\newcommand{\citepfy}[1]{\citeauthor{#1}\footyearcite{#1}}
\DeclareCiteCommand{\footyearcite}[\mkbibfootnote]
{\usebibmacro{cite:init}%
\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{citeyear}}
{}
{\usebibmacro{cite:postnote}}
\begin{document}
\citepfy{Test}
\printbibliography
\end{document}
You need to insert \nopunct into appropriate places for these two different problems.
For the year, this is in the biblatex macro issue+date and you can insert it before the final \newunit:
\renewbibmacro{issue+date}{%
\printtext[parens]{%
\iffieldundef{issue}
{\usebibmacro{date}}
{\printfield{issue}%
\setunit*{\addspace}%
\usebibmacro{date}}}%
\nopunct\newunit}
For the see note, it should be part of your redefinition of footnote:cite after your closing parenthesis. I would also suggest moving the opening parenthesis into the same block.
Putting this into your code, we get:
from
\documentclass{scrartcl}
\begin{filecontents*}{mybib.bib}
@BOOK{Abook,
author = "First Author and The Second Author",
title = {The Longtitle and not the Shorttitle},
shorttitle = {Shorttitle},
publisher = "The Publisher",
address = "Address",
year = "1965"}
@article{Aarticle,
Author = {Article Author},
Journal = {Journal Title},
Pages = {113-126},
Title = {Title of the Article},
Volume = {65},
Year = {1968}}

Best Answer
It might depends on the specific style used, but for standard
biblatexauthoryearstyle, one should be able to remove the punctuation after the year withand to prevent the journal title to be printed in italics, the following should do the trick
