There's stacks, it's an absolute paradise.
Austrian Alpine Club and Kompass maps have recommended / popular ski touring routes marked. This is the Kompass one you need:

If you are can afford / are interested in a guide for a day or two, I can highly recommend Peter Bacher of Rock and Snow. Did a powder technique course with him a few years ago and he was great.

I've only done lift served off piste in the area, so can't recommend actual tours, but for list served stuff the Grüblspitze SE ridge is a short walk from the lift, superb and very safe. The "Schwarze Pfanne" from the bottom of the Hintertux Glacier down to the valley used to be great in good powder conditions but I believe they piste it these days. Pity.
Hopefully somebody with more experience of actual touring in the area will be along shortly. For example I know there's some molto wild & serious stuff off the back of the Hintertux Glacier, but I can't offer any actual knowledge of it except that it exists.
