Soak the dried black beans overnight in plenty of water.
Drain and rinse the soaked black beans. Transfer them to a blender or food processor with turmeric, cumin, garlic cloves, smoked paprika, salt, and pepper.
Pulse until completely smooth (about 3-5 minutes). If too thick for your preference, you can add more water as needed.
Divide the black bean mixture into four equal portions. Form each portion into a patty shape using wet hands to prevent sticking. Press down lightly with fingers or back of spoon.
Heat grill pan over medium heat and cook patties for about 4 minutes per side, until golden brown.
Serve on buns (or lettuce leaves if opted out) as desired.
