Heat a large stock pot or dutch oven over medium low heat and add the oil, onion and garlic to the pot. Simmer, tossing frequently until the onion and garlic are soft and fragrant - about 3 minutes.
Season onion and garlic with the salt, pepper, and smoke paprika. Toss and continue simmering for another 2 minutes.
Pour the cubed potatoes, lentils, vegetable broth, and water into the pot. Increase heat to high and bring mixture to a boil. Reduce to a simmer, cover with a lid and simmer for about 30 minutes.
