Put vegan ham in a medium-sized casserole dish or dutch oven. Cover and bake for 1 hour and 15 minutes.
While the ham is baking, make the maple brown sugar glaze. In a small bowl, combine maple syrup and brown sugar. Stir to evenly mix. Then set aside.
Remove ham from oven. Coat it with maple brown sugar glaze by spooning or brushing it on. If you like, push the optional cloves into the top of the ham. (The cloves don't add much flavor, but the final appearance for serving is fun.)
Return the glazed ham to the oven. Bake uncovered for 15 minutes, and then serve. (If you're using the optional cloves, remember to remove them before eating.)
Not all brown sugar is vegan. However, organic brown sugar is guaranteed not to have used bone char for the refining. You can also look for a denotation on the bag of some brands.
