If Israel just annexed the West Bank and Gaza, would they have to let the indigenous population become citizens (voters)?
It would depend if they were Jews or not.
That's not a flippant sarcastic answer, that's really the way it is. Were they Jews they could become citizens almost immediately because of the Law of Return. If they weren't they'd have to go through the naturalization process unless they provided a blanket amnesty of some kind. If they were to be naturalized it'd take about five years or so.
Edit: That all assumes they annexed them wholesale and not as protectorates or whatnot.
