Bluegill,
I have smoked goat twice, about 5 lbs each. I used Cookshacks chicken rub, real heavy. A full box of wood, about 7 or 8 oz, and smoked it till it got to 180 degrees internal. Like Tom mentioned 1 hour per lb at 225 degrees. After 30 minutes rest, sliced it and the bark that fell off was wonderful. Goat is one of the few meats I serve with White BBQ sauce. Lost my source
and now smoke legs of lamb in place of goat.
