How do I add a SEEK frame while adding the id3v2 tag of a .mp3 file using ffmpeg?

As far as I know, this is not possible with ffmpeg. It seems that manually setting this frame is not useful anyway, since the ID3v2 writing library should take care of properly specifying it.

Which id3 tags can be added using FFmpeg?

There is an extensive overview of which ID3(v2) tags can be written with ffmpeg and what the respective <key> is, since ffmpeg's keys and ID3(v2) keys are not equivalent. You can also have a look at the id3v2.c source file to check the available tags and their metadata key.

What are the commands to do so?

Generally, you specify metadata values by using the -metadata <key>=<value> option, e.g.:

ffmpeg -i <input> -metadata title="Foo" -metadata artist="Bar" <output>

Note that ffmpeg doesn't throw an error if you use a tag that does not exist in the ID3v2 specification.
