You can't. Environment variables are local to processes (and may get
inherited by child processes, but that doesn't help here).
You can do something like (warning: untested code ahead):
PATH=$(echo $PATH | sed 's|/usr/local/lib/TeX|/usr/local/teTeX|')
You could stick this in a shell function (possibly autoloaded) or an alias.
