Here's one I tried for ribs. Tasted pretty good, I just didn't enjoy the chocolate and rib combination. might be worth a try or adapted to what your looking to smoke.

3 to 6 canned chipotle peppers with 1 tablespoon of their juice
1/2 medium onion, coarsely chopped (about 1/2 cup)
2 cloves garlic, coarsely chopped
1/4 cup chopped fresh cilantro, plus 1/4 cup chopped cilantro for
garnish
1/2 ounce semisweet chocolate, coarsely grated or cut into pieces
2 strips (each 1/2 by 1-1/2 inches) fresh lemon zest, coarsely chopped
2 tablespoons brown sugar
1 tablespoon pure chile powder, such as ancho chile powder
2 teaspoons coarse salt (kosher or sea)
1 teaspoon lemon pepper
2 to 3 tablespoons vegetable oil
2 racks baby back pork ribs (4 to 5 pounds total)
Lime wedges, for serving
You’ll also need:
Place the chipotles and their juice, onion, garlic, 1/4 cup of cilantro, chocolate, lemon zest, brown sugar, chile powder, salt, and lemon pepper in a food processor and puree, adding enough oil to make a thick paste.
Using a rubber spatula, spread the chipotle paste on both sides of the racks. Cover the ribs with plastic wrap and let marinate in the refrigerator for at least 4 hours or as long as overnight. The longer the ribs marinate, the richer the flavor will be.
Transfer the ribs to a large platter or cutting board. Let the ribs rest for a few minutes, then cut the racks in half or into individual ribs. Sprinkle the ribs with the remaining cilantro. Serve at once with lime wedges.
Variation: How to cook Chipotle Chocolate Ribs in a Smoker: Set up and light the smoker according to the manufacturer’s instructions and preheat to low (225 to 250 degrees F). Place the ribs in the smoker bone side down and smoke until cooked through, 4 to 5 hours. You’ll need to replenish the wood chips or chunks after the first and second hour of smoking and to replenish the coals every hour.
