I am using LyX with bibtex and natbib for my citations. However, for some reason when I create the pdf, the citation comes out as Author [year] instead of Author (year). Is there a way to change the style of the parenthesis?

With etoolbox you can patch the command natbib uses to set all non-numeric citation labels: \NAT@citex. The postnote is passed to \NAT@citex as the second argument (#2). For \citet and its variants \ifNAT@swa will expand <false>, \ifNAT@par expands <true> and \NAT@date is defined.
\documentclass{article}
\usepackage{natbib}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\NAT@citex}
{\ifNAT@swa\else\if*#2*\else\NAT@cmt#2\fi
\if\relax\NAT@date\relax\else\NAT@@close\fi\fi}
{\ifNAT@swa\else\if*#2*\else\ifNAT@par\else\NAT@cmt#2\fi\fi
\if\relax\NAT@date\relax\else\NAT@@close%
\if*#2*\else\ifNAT@par\NAT@cmt#2\fi\fi\fi\fi}{}{}

A well-known bibliography style that generates authoryear-style citation call-outs and uses & as the conjunction if the bib entry has exactly two authors (or editors) is agsm. This bibliography style is part of the harvard citation management package, but it's compatible with the natbib package as well.
