Preheat oven to 425°F (220°C).
Place the halibut fillets in a baking dish or on a sheet pan lined with parchment paper.
In a small bowl, whisk together the olive oil, lemon juice, salt, black pepper, paprika, smoked paprika, and garlic powder.
Brush or spoon the mixture evenly over the fish.
Bake for 12–14 minutes, or until the halibut is opaque and flakes easily with a fork.
Serve warm with salad, quinoa, pasta, couscous, or your favorite sides.
