Can I install some kind of exhaust fan to vent those odors and fume to the outside without affecting my heating and air conditioning, would a bathroom type venting fan work or would a larger system be required?

Probably. How much square/cubic footage is your shop area? Do you have a window in your work area, to modify, maybe for a fan or other exhaust (and air intake?) unit.

If practical: Consider an intake air supply, also, rather than the outgoing ducting removing the AC/heated air. Close the AC/heat vents prior to finishing, at least for some circumstances.

Also, possibly, drape off (temporarily) your finishing area, so that the fumed air flow would be mostly/best guided toward the exit fan, only.... i.e., least amount to mix with the fresh air, coming in.
