If you dig incense/smoke/fire offerings then ask your lama to give you the riwo sang chod (Mountain of Pure Offerings) practice by Terton Lhatsun Namkha Jigmed. it's a good excuse to generate vast clouds of smoke (and offerings). It is a fairly short practice and in combination with prayers to Guru Rinpoche does a hell of a lot of work!
Normally it is carried out during/before retreats to keep obstacles at bay.
I do it almost every day.
If you do it with fire (you can use incense charcoal or sticks for the daily practice) it's a good opportunity to burn worn out or destroyed texts, prayer flags, etc... so that their blessing goes out to all beings.
