Preheat a smoker to 275°F. In a large bowl, combine the ground turkey, egg, breadcrumbs, onion, jalapeño, 1 tablespoon of the ketchup, Worcestershire sauce, smoked paprika, salt, and black pepper. Mix gently just until combined.
Shape the mixture into a compact loaf on a piece of foil or a smoker-safe tray. Lay the bacon slices across the top, tucking the ends underneath the loaf. Brush the bacon with the remaining 1 tablespoon of ketchup.
Toss the sweet potatoes with the olive oil and garlic powder. Spread them in a single layer in a smoker-safe pan.
Place the meatloaf and sweet potatoes in the smoker. Smoke until the center of the meatloaf reaches 165°F and the sweet potatoes are tender, turning the potatoes once for even cooking. If the bacon needs more color, briefly move the meatloaf to a hot grill or broiler until browned.
Let the meatloaf rest for 10 minutes before slicing. Serve with the roasted sweet potatoes.
