You can use the method in the following post. If you don't want to use the T-shirt you can skip that step, but I think it is unique and it does serve a purpose. Also just think about the conversation you can have. Just note that the preparation takes several days:T-Shirt Double Smoked Ham
With fully cooked hams, others have just placed the ham in 200°F - 225°F smoker, and applied four hours of smoke, then moved them to the oven or kept them in the smoker until they reached an internal temperature of 140°F. If you want to add a glaze to a ham that has been fully cooked in the smoker, I just recently saw a show that demonstrated how one company adds a glaze to their fully cooked ham. They would apply a glaze and use a torch to caramelize it; being careful not to burn the sugars. They would repeat this step in layers until the had a nice thick glaze. If you are going to attempt this I would practice glazing a chicken first, you don't want your first experiment to be your ham.
I'm not familiar with the ham you are referring to, but if it is packed in a brine, make sure you pat it dry prior to placing it in the smoker
