Default Clearance ?
Should there be some clearance or flashing between the soffit hardy board and the exhaust vent for the furnace?

Yes there should be.
Hot flue and wood make fire and with zero support it must be touching.
Most gas flues require one inch space.

What type of furnace is it?

NFPA 54 has info on flue clearances, but I believe PVC is the only allowed zero clearance flue.
