Torah Study is self-explanatory.
Lay led I'm not sure, but:

Through a google search. The only memory I have of synogogue was two years ago for my brother's bar mitzvah, which was after the normal services. Guys read in Hebrew for a while from the Old Testament, then there's a service in English not unlike a church service. The one I went to was very informal, and there were people openly challenging the rabbi and walking around. If they take out the Torah that's a big to-do as well.
Also if your group has men you won't be able to sit with them.
