Sort and wash peas; cover with water to 2 inches above peas, and set aside. Heat 1 teaspoon of oil in a Dutch oven over medium-high heat. Add the onion, carrot, and bay leaf; sauté 5 minutes, stirring frequently. Add 2 teaspoons garlic, 1 teaspoon rosemary, paprika, and pepper; cook 3 minutes. Add the tomato paste and soy sauce; cook until the liquid evaporates, scraping the pan to loosen browned bits.
Drain the peas. Add the peas, 4 cups of water, and vegetable broth to the onion mixture; bring to a boil. Cover, and reduce the heat to medium-low; simmer 1 hour (or more-- until peas are tender), stirring often. Discard the bay leaf. Place half of the soup in a blender or food processor; process until smooth. Pour the pureéd soup into a bowl. Repeat the procedure with the remaining soup.
Combine 1 teaspoon oil, 1 teaspoon garlic, 2 teaspoons rosemary, and parsley. Stir the parsley mixture into the soup. Spoon the soup into bowls; top each with 2 teaspoons of sour cream.
