Is this an already smoked or just cured, raw ham? Smoked, all you're really doing is reheating and maybe adding a glaze, etc. Smoking a raw ham is pretty much like smoking a pork shoulder/butt, but you only want to take it to an internal temperature of 145 as going further will just dry out the cured pork.
Here's my first attempt of a raw ham that I cured and smoked. It regrettably was boneless, but that's all I could find that was uncured and unsmoked.
