I have been asked to do a ten minute presentation at an interview, any advice please?

hi all, I have been offered an interview for a new job, the email the employer has sent has mentioned an interview panel and giving a ten minute presentation on what is good customer service/challenges in managing a small team. I have never had to deal with an interview panel, and I have never done a presentation. Can anyone give me any advice or tips please? As if any ordinary interview wouldn't be nerve racking enough. Thanks in advance:)
