I've double smoked a ham many times using the following recipe that I came across a few years ago. I made a few minor adjustments to suit my smoker, a Cookshack electric. Otherwise, I've stayed true to the recipe and everybody raves about it.

Ham should be a fully cooked or partially cooked ½ shank variety or can be shoulder variety (water added can be used, as long as the water added does not exceed 23% water added product.) If it is pre-smoked with hickory, that seems to work out best.
Glazing Sauce:
½ cup brown sugar
¼ cup maple syrup (use dark grade B real maple syrup if available)
¼ cup honey
2 Tbsp cider vinegar
1 – 2 Tbsp Worcestershire sauce
2 Tbsp instant coffee granules (use a good brand because it makes a difference)
1 Tbsp dry ground mustard
2 Tbsp orange juice concentrate (a good brand provides better flavor)
Blend all ingredients in a sauce pan with a wire whip and heat slightly until everything combines into a viscous or thick looking sauce.
Place water soaked chunks of mesquite, hickory or pecan (we prefer the smoke of pecan over all the others) on coals 5 minutes before putting ham on cooker. This will allow the ham to obtain maximum smoke flavor during the second cook cycle. (the first cook cycle is the cycle the processor uses.) If even more smoke flavor is desired, place ham in freezer for 1 to 1 ½ hours prior to cooking to allow outer edges of ham to start to freeze. Go easy on this procedure, you don’t want the ham frozen hard!
Maintain temperature of cooker/grill at 225° to 250° during cook cycle. Cook for 25 to 30 minutes per lb. until internal temp on the ham shows 140°. Baste ham with glazing sauce every 10 to 15 minutes during the last hour of cooking time. Glazing compound will burn, so do not start glazing the ham until the internal temp of the ham reaches 120°.
Note: Use an injectable marinade such as Tony Chachere’s Pecan-Honey-Praline in the ham just before cooking to “explode” the flavor of the ham. Be sure to use it @ the recommended rate of 2 fl. Ozs. per pound of meat. It really does take that much to do the job right!
