Preheat your smoker to 275°F (135°C). Use a sweet fruitwood like apple or cherry for a gentle, smoky aroma.
Prepare the glaze by whisking the brown sugar, bourbon, maple syrup, vinegar, and smoked paprika in a small saucepan over low heat until the sugar is fully dissolved.
Prepare the ham by placing it flat-side down in a disposable aluminum foil pan to catch all the sugary juices.
Baste the meat by brushing about half of your bourbon mixture all over the exterior and tucking it between the spiral slices.
Smoke the ham for 2 to 3 hours, or until a meat thermometer reaches an internal temperature of 140°F (60°C).
Apply more glaze every 45 minutes during the cooking process to build that thick, mahogany-colored crust.
Rest the meat for at least 15 minutes under a loose foil tent to ensure every slice stays succulent.
Drizzle the remaining syrup from the bottom of the pan over the platter just before serving to guarantee a sticky, glossy finish.
