I like Paul's voice for Vision, but they shouldn't use JARVIS to make him. He should start as an underling of Ultron that turns to the side of good. It'd give the character a better sense of purpose plotwise.
As to what Jarvis would look like, probably a hologram of a featureless humanoid. Unless if Tony wants to make him look like an old butler as a nod to the original Jarvis.
