Add the lemon juice, olive oil, Greek yogurt, hemp seeds, and sesame seeds to a blender or food processor. Pulse 2-3 times to combine.
Add the drained and rinsed chickpeas, garlic powder, cumin, and salt to the blender.
Blend on high speed for 30-45 seconds, stopping once to scrape down the sides with a rubber spatula.
If the hummus is too thick, add 1 tablespoon of cold water and blend again. Repeat with a second tablespoon if needed. For a thinner consistency, add water 1 tablespoon at a time.
Taste and adjust seasonings. Add more salt, garlic powder, or lemon juice as desired. Blend again briefly.
Transfer to a bowl or airtight container. Drizzle with olive oil and sprinkle with paprika or extra sesame seeds if desired.
