I'll add a few relevant and less relevant references: This discussion [1] is about extending drracket's built-in indenter, using `drracket:indentation` [2]. The #lang's get-info function should accept that symbol as a key, and return an indentation function.
To access the default indentation by drracket, it seems you could call `compute-racket-amount-to-indent` [3]. It accepts an optional argument `get-head-sexp-type` which should be a function mapping identifiers to one of #f 'lambda 'define 'begin 'for/fold 'other, where #f means that it will use the built-in list. There was some discussion in [1] and in this mailing-list discussion [4] about the future possibility of using syntax properties or a similar mechanism to allow macros and other identifiers to specify their indentation.
