(Edit) Ok, so you don't want to make the gerund/infinitive passive, you just want to make the sentence passive. Got it.
The passive voice sounds awkward in this context, and would not normally be something a native speaker would say. Still, if you are determined to do so, the rule is generally the same. Invert subject and object, and change the verb to the passive
Watching TV is enjoyed by me.
Playing football is not liked by me.
To play football is not wanted by me.
To drink a cup of tea is not wanted/desired by me.
Again, all of these are very unusual. In general, we do not use the passive voice for verbs of emotion or perception such as want, like, desire, think, enjoy, etc. -- but there are exceptions. For example, in a formal context, this kind of sentence sounds fine:
The sumptuous meal was enjoyed by all the guests.
Original answer, for general interest
"Being watched" is the passive of "watching", and "being played" is the passive of "playing", but neither really works in this context. With verbs like "enjoy" or "like", you would need an activity where you are the object of the gerund. For example:
I enjoy someone else cooking for me ⟶ I enjoy being cooked for (by someone)
I enjoy someone else singing to me ⟶ I enjoy being sung to (by someone)
