My reasons for these stunts and abilities are thus:
1. I added the aspect
That Voodoo That You Do So Well because it's freaking awesome.
2. The mortal stunt is so that his Lore is boosted when working with Vodou knowledge and specifically when dealing with Loa.
3. I gave him some Wizard abilities: Sight/Soulgaze, Channeling w/ Spirit (you said that he was mostly a Thaumaturgist), and full on Thaumaturgy with specialization in Necromancy. I also included some Lawbreaker Stunts to boost his Necromancy.
4. I gave him Ghost Speaker since it is normally within a Vodou Priests purview to interact with the spirits and loa.
5. That is also the reason I gave him Modular Abilities. It is well recorded that in rituals, Vodou Priests try to become possessed by the loa. This Modular Ability power is for any physical abilities the Loa may wish to impart on the priest while Possessed.
(This is an extrapolated ability I got the idea for from Morty in Ghost Story.)
6. I also gave him Domination so that he can create Renfields. I consider them to be traditional Vodou zombies. They aren't undead, they just aren't themselves as they are under the control of their priest.
7. I added Guide My Hand because at the end of the day, he is a priest of a religion.
