I'm not exactly sure what you mean by beyond basics methods, can you show me an example course you've seen for a different language?
As far as learning Tagalog goes, courseware is thin on the ground, I used a mixture of Pimsleur, Tagalog for Beginners, italki, and my friends. The last one was invaluable to me for picking up how Tagalog is actually spoken.

I used this one when I was in country. Picked it up pretty easy, but of course, I was around it 24/7
