It's really easy to find a job as a lab tech, if you dont mind not getting paid (ie internship). Just email PI's using the subject heading "Free Labor." Put your cover letter in the text of the email, and attach your Resume. You should get a dozen replies within the hour.
If you want to get paid, that's a whole other issue, since there are a slew of foreign graduates willing to come here and work for little more than their work visa, in hopes that they can go to grad school here.
Look at Human Resource pages for colleges in your area, or areas you wouldnt mind moving to. There should be quite a few positions open now, since people leave for the summer, head off to grad school, etc.
If your going to be a Lab Tech, it doesnt really matter what the lab researches, since your duties will revolve around cleaning beakers, etc.
If you want to get a little more involved in the research, look for Research Tech positions. You'd be doing a lot of the grunt work for grad students/post docs (ie running gels, PCR, transfection, etc), but once you get your feet wet the PI might be willing to let you take on your own project (in addition to all the other work you've been doing of course). These pay more, but are harder to get.
You could get a job at a big BioTech firm like Pfizer, just don't expect it to be anything too hands on. (A friend of mine did this one summer and she was in charge of weighing out how much food the mice ate.)
