I did it volunteeringly. Describe the venue, how many people, setup (e.g. how many parallel tracks), what went well, types on attendees and sponsors. Was it very commercial or community driven? Then a list of presentations I visited and 3-5 bullet points unless a presentation was extra interesting. With an audience of 20 people I can't remember ever receiving a follow-up question so I wouldn't overthink the format, style or level of detail of such a report.
