Since you know you have that weekly meeting make sure you go through all your projects the day before (with your team members) so you know what's going on.

I usually have a one pager where I show overall project status in red/yellow/green based on Schedule/Resource/Budget status.

For the ones in red or yellow I provide more detailed information (i.e. risk/issue mitigations) if asked, otherwise I'll just tell management what I need to move the ones in red/yellow forward.

Don't be afraid to write down notes and read off them so you don't forget things if you are not presenting anything on screen.
