The easiest way to get invited to speak at events is to speak at other events and be recommended by word-of-mouth. A great way to get started is to contact organisations in your local area that regularly have speakers. It could be at a university or student group, networking event, meet-up, industry gathering, or corporate event. After a bit of practice, if you do a good job, you will soon be invited to speak at other events. Good speaker coaching can help you through this difficult first phase.
