I want to have a vector with a superscript:
\vec{o}^t
But this gives very bad results: the t is overlapping with the vector arrow. How do I fix this (and why does this give bad results in the first place) ?

Here is a comparison of a few techniques to represent a vector (not sure about the \overline, \underline ones as I don't think that that is standard usage):
Code:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$\vec{x}$ $\overline{x}$ $\underline{x}$ $\mathbf{x}$
$\vec{\mathbf{x}}$ $\overline{\mathbf{x}}$ $\underline{\mathbf{x}}$
\end{document}
Priming a vector denoted with the arrow is, as you discovered, not a really good thing to do. You want to prime the letter, not the whole construction.
\documentclass{article}
\newcommand{\pvec}[1]{\vec{#1}\mkern2mu\vphantom{#1}}
\begin{document}
$\vec{p}+\pvec{p}'=\pvec{p}''$
\end{document}
Best Answer
I don't really know why the result is bad; I suspect it has to do with the width of the letter. I wouldn't use such a notation, but that's a personal opinion.

the superscript is moved a bit to the right. One might perhaps let TeX do some computations in order that the shift to the right of the superscript is automatic.
