In a medium bowl, combine the ground lamb, Greek yogurt, garlic, kosher salt, black pepper, onion powder, ground cumin, and cilantro.
Using a 1.5-tablespoon scoop, measure out even portions of the mixture onto a plate. I usually end up with 16 meatballs. With wet hands for easier handling, shape each portion into a round meatball.
Heat the olive oil in a large (12-inch) lidded skillet over medium-high heat until it shimmers and becomes fragrant, for about 2 minutes.
Add the meatballs in a single layer and cook them, turning frequently, until golden brown, for about 5 minutes. If the oil becomes too hot, lower the heat to medium.
Add ¼ cup of water to the bottom of the skillet. Cover with the lid and cook the meatballs until they are cooked through, about 2-3 more minutes.
Using a slotted spoon, remove the meatballs from the skillet to a serving plate. Serve immediately.
