If you want a list of the coefficients, try something like this:
(%i15) dexp : expand(diff(exp,e))$
(%i16) makelist(coeff(dexp,s),s,[diff(v(e),e), diff(u(e),e)]);
(%o16) [a*u(e)^a*v(e)^(a-1)-(a*u(e)^(a-1))/v(e)^a+u(e)^(a-1)/v(e)^a,a*u
(e)^(a-1)*v(e)^a+a*u(e)^(a-2)*v(e)^(1-a)-u(e)^(a-2)*v(e)^(1-a)]
Also, you might like to read the user documentation for ratexpand and
ratcoef.
