well you are a human which prings you up to you skills per level equaling 3+int, then your favored class bonus can be in either health or a bonus skill point which would be 4+int skills, if you take the fast learner feat then you can have the bonus be 1 health and 1 skill point per level, also if you take the improvisation feat (these are both human only feats) you get +2 to all skills that don't have a rank in them and can use any skill untrained, then take improved improvisation making that bonus +4
rangers just get a bonus to track, fighters can track to, also bounty hunters try and take their target alive so extra damage to humanoids would be pointless if that's what your going for. (Because bounty's are typically higher if the target is alive then dead)
For Pathfinder, I'd go with a Fighter/Rogue, the abundance of Feats and Skills that will assist you in tracking down your quarry. As for race, it would be either Human (extra Feat and Skill Points) or Elf.
Once you've cornered your target, I would go for a decent mix of ranged and melee Feats. However, I would go for things more along the line of Improved Trip and Improved Disarm, to control the fight.
In Chaos 6010, there's two options for what you're looking for... there's both a Bounty Hunter class and a Tracer class.
