Most likely differs a lot between traditions like the Copts, Syrians and Greeks.
If you go to a Byzantine Catholic church (Ukrainian, Ruthenian, Romanian) there are several jurisdictions sharing the Byzantine-Slavonic rite (with slight variations), so if they celebrate vespers it should be similar between them.
I recall many (or perhaps most) Eastern Catholic parishes did not actually do vespers, in that respect they were a lot like RC parishes with Saturday night Masses. This situation may have changed in the last six years, but I wouldn't be willing to bet either way.
The parish I belonged to was one of the few which did introduce vespers, and the priest had to teach the congregation about it. The tradition had almost completely died out in the diocese but the pastor (one of the younger priests then) probably learned how to do it in seminary, or perhaps when he studied in Rome.
The best way to deal with this is to get the phone listings and call around. Ask the priest "what time is vespers?" It will get you in touch with the apostolic roots of the church, and the hours is still the official prayer of the church, the full cycle is also very catechetical (if it is in the vernacular).
I found a Russian Catholic Church of the Byzantine Rite and they have Saturday Vespers. So I might be checking that out maybe tomorrow!
Are there any prostrations during vespers? Are people mostly standing? Any tips would be helpful.

I was a little surprised at the appearance of the church. I expected there to not be a lot of pews. Do Eastern Catholic churches pretty much look like Roman Catholic Churches but with Eastern art and icons?
