Ive been on several sites, all of which offer texts with instructions and offering substances for Chod and Sur offerings, and in the Nyingma school these are fine for lay practitioners, you can even practice the Thousand armed Chenrezig within the Sur offering ceremony. But is this advisable for a student of the Kagyu school?
Sur, at the least, is a very easy aroma offering to those in the bardo, and hungry spirits, but is transmission required, or atleast an Empowerment for the practice of Thousand Armed Chenrezig?


, maybe some students from other lineages can help.
