1. you need to have something you really want people to know about, develop a talk around it

2. start doing that talk at your local meetups, you'll figure out how to do talks well with time (also there is good advice online)

3. identify conferences you'd like to speak at, and answer their call for talks

4. keep doing all that, and at some point one of your submissions will be accepted

5. rehearse many times to be prepared, and do a good talk

6. more submissions will be accepted, and if you keep doing a few conferences a year, eventually you'll get invitations to speak at conferences
