It depends on what other equipment you have, since exercises fit into a routine with each other. Just dumbbells? Then dumbbell overhead press, bent-over rows, goblet squats, and Romanian deadlifts will give you a full-body workout. Do you have a bench? Then your options expand a little and you can add dumbbell bench pressing.
And are we talking about little 3 lb dumbbells or something decently heavy? If they're super light, you'll want to rely more on bodyweight exercises and use your dumbbells for assistance exercises like lateral flyes.
