Think about previous roles you've held, and consider if the people who reported to you had ever thanked you or complimented you for something. Any kind of positive feedback you can remember from a coworker under you would make for a great examples for this question. Tell the interviewer two or three things that your direct reports have thanked you for or given you positive recognition for. When in doubt, think back to your past performance reviews. Share the positive feedback you received about your leadership style. Be sure to tell the interviewer that your direct reports or past managers have told you they liked these things about you and your leadership; it will surely impress!

"My direct reports would tell you that I'm a very positive and encouraging leader who knows how to keep them motivated. I insist on building positive relationships with people I'm responsible for. I do this by showing them respect and acknowledging and rewarding the good work they do. In a previous role, after holding a mid-year review with a team member, she mentioned to me that she appreciated how approachable I was and that my openness to feedback made her feel comfortable to share ideas that may improve our systems.
On the other hand, if they're not performing to standards, I make sure they know what the standards are, and I help them improve to meet those standards."
