Good luck 9ason- it sounds like you may have a core group you can rebuild around. And it's great you have a spot for meetings- that's been a big issue with some clubs I've been in. A website will help too- you'll probably get a lot of new members from that.
Some other projects some clubs do is help build/maintain fishing access for the handicapped (Project Access) and help out dept of fish and wildlife folks with stocking etc- maybe the Texas dept has a PR
person that you could contact to piggyback on events they might have to recruit new members, and/or find out about volunteer opportunities for projects. F&G folks like area fisheries biologists can also make good speakers for meetings.
You might also give some thought to affiliating your club with a national group like the Federation of fly Fishers. www.fedflyfishers.org
clubs seem to operate pretty autonomously but they'll help give the club more exposure-- and it's a good way to network with other folks with leadership roles in clubs that may have dealt with the some of the same issues and do joint projects/trips etc. You can do a search here to see if there is already one on your turf: http://www.fedflyfishers.org/Default.aspx?tabid=4357
