About 3/4ths of my basement is finished into a family room, the
remaining 1/4 has been walled off for my wood shop, this gives me
the comfort of air conditioning and heating. My problem is the
odors and fumes created when refinishing my wood projects are going
through out the house. Can I install some kind of exhaust fan to
vent those odors and fume to the outside without affecting my
heating and air conditioning,

As Sonny suggested, you have to consider where the air is
coming from to replace what you are venting to the outside.
If it's coming from the air conditioned/heated part of the
house, then yes, it will affect your heating and AC.

would a bathroom type venting fan work
or would a larger system be required?

Depending on what your fumes are and their intensity, you
might need a fan rated for flammable vapors.

Ideally you'd have two fans, or a two speed fan - so you
can have a higher flow rate while you're actually doing
the finishing work, and a lower one while the project is
drying (e.g. overnight).
