Examining the 1996 edition of the IPA chart, I see no symbol for a lateral
nasal (and the symbol you describe is not there either).  So I guess you'll
have to make up a symbol, using the system of IPA diacritics.  Four options
spring to mind:

(1) If the sound is best thought of as a nasalised lateral liquid, then you
could use [l] with a tilde over it to indicate nasalisation.

(2) If the sound is best thought of as a nasal stop which has a lateral
release, then you should probably use [n] followed by a superscript [l]
(the symbol for lateral release).

(3) If it's the other way round--a lateral liquid which has a nasal
release--then you could use [l] followed by a superscript [n] (the
symbol for nasal release).

(4) If it's a double-articulated sound, you could use [nl] with the two
symbols joined by a tie-bar.

Which option you choose will depend partly on the phonetic details of
the sound in question, and partly on how the sound fits into the overall
phonological system you're going for.  If your lateral nasal is treated
as a nasal-ish kind of lateral, then (1) or (3) would be your best bet.
If it fits in with the nasal series, then (2) is your best bet.  If neither
(or both), then perhaps (4) would work best.
