I think this should be pretty simple but I just cannot find the right words to describe it to Google.

I have a protocol for which I am writing a dissector in Lua. My packets consist of header and payload. I can mark some part of my header as int (eg. payload length) or flags (eg. type of message). As for the payload I would need to mark it as a given protocol that already has dissector in Wireshark (in my example TLS or more specifically Record Protocol format). How do I do that?

Basically you create a subset of the TVB, with the payload data, and hand that to the dissector which can dissect that payload. In order to do so you have to get the handle of this dissector fist.

PS: not a Lua programmer, but this is the gist of it.
