There are multiple sites for french conjugations (Bescherelle, Larousse etc.), but they rarely include the pronunciation.

I found reverso which inculdes the pronunciation as a sound (click on the speaker icon).

There’s also the CNRTL site’s Morphologie tab where one can enter any verb or conjugated form obtain the phonetic (in a strange but understandable phonetic alphabet) :

I think the second one is better for you as you can see the phonetic for multiple forms at once without clicking each one (the sound does not seem to work in Firefox, though).
