In small bowl, combine chipotle chili powder, hot smoked paprika, garlic powder, lime zest and juice, and olive oil. Stir to blend. Evenly spread over tops and sides of salmon fillet steaks. Place skin side down on baking sheet. Bake in preheated oven for 4 to 6 minutes for 1/2 inch thickness of salmon. Salmon is done when it’s still a tiny bit pink in the center. It will continue to cook as it rests.
