Suggestion: load "mactex-utilities" and look at its source.
It might help you get started with the changes you would like
to make.
(%i1) m : matrix([a,a/b])$
(%i2) tex(m);
$$\pmatrix{a&{{a}\over{b}}\cr }$$
(%i3) load("mactex-utilities")$
(%i4) tex(m);
$$\begin{pmatrix}a & \frac{a}{b} \\ \end{pmatrix}$$
