What about humanoid human for punishing those evil necromancers that create those foul beings?
Undead favored enemy with whip proficency and a belt full of holy water :D
on topic: I have found it odd from a RP standpoint when players take favored enemy humans. So either the player hates certain humans and knows how to hunt them, or they are detached and don't mind carving up whoever is in their way and know how to do it best. creepy!
You could try going with constructs too, another group of creatures that have false life.

There's a lot of way to rationalize it: You're a hunter, so you know how to hunt, most prominant race is human (and you may be human) so you probably know a lot about them.
If you were in a war, you probably fought against humans.
If you were around human settlements, you probably had to track lost humans.
Favored enemies dont mean you hate and want to kill all of that creature type. It simply means that you are good at killing them. As for undead hunter, maybe a repated monster would be good, such as ghosts or vampires.
It's really dependent on campaign, frankly. What have you been running into a lot? What hints does your DM drop about upcoming Big Bad Guys?
Did Pathfinder lift the requirement of being Evil, when selecting your own race as Favored Enemy?
As said, it is really campaign dependant.
Having said that, every time I have played an undead heavy campaign there wer also always lots of evil outsiders and constructs. Humans are also nearly universal.
So without knowing the campaign those would be my 3 suggestions: evil outsiders, constructs, and humans. Choose your own order.
Best bet is to do undead, human, outsider (evil), and the last one can be more campaign specific. (what you tend to run into a lot).
