The chapel I have attended in my city for the EF provides a small blue-covered handbook that contains the Order of the Mass; including Rites or actions specific to either the Low Mass or High Mass.
It also includes suggestions for prayers before Mass, Pre and Post Communion, as well as prayers said after Mass by the congregation. Interestingly, the booklet includes prayers omitted from the 1962 Missal - which are ‘bordered’ and captioned as relevant to the older Rite. I’m not sure whether they can be optionally said or not.
