In a medium bowl, whisk together the black pepper, garlic powder, olive oil, soy sauce, and teriyaki sauce until well combined. Set aside a few tablespoons of the mixture in a separate clean bowl for brushing near the end of cooking.



Pat the chicken thighs dry with paper towels. Slice the Polska kielbasa into thick coins so the pieces brown without drying out.



Arrange the chicken thighs and kielbasa coins in a single layer on a broiler pan or a foil-lined rimmed baking sheet fitted with a rack. Spoon or brush the soy-teriyaki mixture over the meat, coating the chicken well.



Preheat the broiler and place the pan 5 to 6 inches from the heat source. Broil in batches if needed for 10 to 15 minutes total, turning once, until the kielbasa is browned and the chicken reaches 165°F in the thickest part. Brush with the reserved clean sauce during the last few minutes of cooking.



Transfer the broiled chicken thighs and kielbasa to a serving platter. Let the chicken rest for 3 to 5 minutes before serving so the juices settle.
