in general aim for repetition and stringing activities together.
So for us, when I first started to do this. Each night they get a 'treat' but to get that treat they first need to be ready for bed - eg bedroom ready to sleep in, correctly dressed/ washed etc..
then after the treat they must choose a calming activity - ideally in their bedroom eg reading (nothing that gets their heart rate up) for 30-60mins then they must bush their teeth
It's this point we say time for bed, but we allow them to carry on reading for another 30-60min then it's lights off
if they don't do the activities/ actions after the treat, then we warn them that they'll not get one tomorrow etc. (and really do what you say)
also you may need to flexible on the activities until they get into the swing of it
