Welcome from Tidewater, VA! I made the same transition as you and had the same tongue burn for weeks. For me, it wasn't a need to smoke slow. I found that packing much looser than I thought, literally just dropping the tobacco into the bowl and letting the nail tamper alone be the pack and then shallow draws. The full draw of a cigar pulls way too much. The paradox is that a hard draw does not result in more of the good flavor you are seeking. I take frequent shallow draws and the flavor difference is profound as well as eliminating the tongue bite.
