One solution would be to put you math definitions into a .sty file instead
of a .tex file so that you can use \usepackage{vlstyle} instead of \input.
 If you put (or symlink) the file in your local texmf path it should work.
 I do this for my math shortcuts and it works fine with org-mode.  To make
it into a .sty file you just have to put \ProvidesPackage{vlstyle} on the
first line of the file, import any dependencies, e.g. amsmath, with a
\RequirePackage declaration and end the file with \endinput. If it is just a
bunch of \newcommand, \renewcommand, \def and \DeclareMathOperator
declarations then there shouldn't be any problem.
