My suggestion would be to head to a local PADI shop and do a refresher course. They can be done in one day and that would give you a pretty good idea wheather or not you needed a full recert. They can also help you get a replacement card.

Careful on the agency bashing, I'm not sure of the requirements for the various agencies when it comes to introductory dives, but instructors who don't follow guidelines are not limited to any one agency.sbrooks:Agreed -
I took a resort course in Mexico. While I felt it was very thorough and well done, considering the minimal time requirements (PADI), I see what I missed when I got home and took my OW Cert (SDI). I don't recall being taught any buoyancy and remember that I was slightly negative during the one dive. I think our max depth was about 40 feet for 35 minutes or so.

As far as PADI and buoyancy, they do show how the inflator/deflator works and they do tell you not to touch the reef with hands or fins and such. The instructor is supposed to take care of the bulk of it for you simply because if they don't you'd probably have divers hitting the surface, or the reef, all of the time. There's only so much you can teach a person on an intro dive, unless you want it to become a full certification.
I'd have to do a bit of research, but I do wonder if SDI, NAUI, YMCA or SSI require buoyancy skills practice for introductory dives... somehow I'm skeptical, but I couldn't say for sure without checking first.
Walter:YMCA has a resort course, it does include buoyancy control. The instructor does not manipulate the student's LPI and dump valve. Students learn to do that for themselves.
