it is always a tough situation when we are thrown into a new environment but it is also an opportunity. Since there are no other facilities near where you are, the students who used to participate in your classes are in the same dilemma because they have no more classes to go to.
If you had a ‘following’, you could contact some of your previous students and offer to teach classes in their houses. The number of participants would limit itself because of space but since they would be paying your directly, you may not come out any worse. You could also offer ‘Walk and Strength’ or ‘Walk and Stretch’. I see that you are from Mumbai and assume that you are not limited by weather concern about possible outdoors options.
But I would definitely first ask the participants you used to teach and see whether they have any interest.
I wish you good luck.
