Season scallops on each side with salt and pepper. In a large skillet, heat 1 tablespoon vegetable oil over medium heat until it just reaches the smoking point. Add 8 scallops to the pan, and saute until golden brown, about 2 minutes per side. Remove from pan to a warm plate. Repeat with remaining scallops.
In a second skillet, heat 1/4 cup vegetable oil over medium-high heat. Add capers, and cook until they open, about 1 minute. Remove with a slotted spoon to a plate lined with paper towels.
Place 4 sea scallops on each of the four plates. Garnish each plate with 1 tablespoon fried capers, 1 tablespoon fresh chopped herbs, and a wedge of lemon. Serve immediately.
