Have you looked over the DAT Bootcamp orgo lab techniques sheet?
Organic Chemistry Lab Techniques
If not, I'd recommend reviewing that sheet since it covers all the main ideas.
Other than that, the best way that I learned the organic chemistry lab tests was from actually doing the techniques in orgo lab. Now, I just visualize the techniques in my head, which helps me recall what each does. If you haven't been exposed to the techniques yet, I'd watch YouTube videos on them to familiarize yourself with how they look and what happens.
