In a large bowl, whisk together the chickpea flour, baking powder, cumin, turmeric, garlic powder, salt, and black pepper until well combined.
Gradually add the water and 1 tablespoon of olive oil to the dry ingredients, whisking until the batter is smooth and free of lumps. It should have a thin, pourable consistency similar to crepe batter. If using chopped vegetables, stir them into the batter now.
Let the batter rest for 5-10 minutes to allow the chickpea flour to hydrate, which helps improve texture.
Heat a non-stick skillet or griddle over medium heat and lightly coat with olive oil. Pour about 1/4 cup of batter onto the skillet, spreading it slightly with the back of a spoon into a 5-6 inch circle.
Cook for 2-3 minutes, until the edges look set and bubbles form on the surface. Flip the pancake and cook for another 1-2 minutes, until golden brown and cooked through. Repeat with the remaining batter, adding more oil to the skillet as needed.
Serve warm, topped with fresh cilantro or a dollop of yogurt if desired. Enjoy your chickpea flour pancakes as a savory breakfast or light meal!
