Another way is to write ties inside the chord and set lower tie's direction.
\relative c'' { \voiceOne <a a'>4 <b b'> <cis_~ cis'~> q <d d'> }
I think it's the best way of doing this because:
- it is more structurally correct than tie-configuration (won't break
when music is transposed, and you don't have to care for correct upper
tie positioning)
- it is shorter than reverting tie direction.

Somehow i don't like this solution...
I wrote a small scheme function that could be used when the triplets
are simple (i.e. consisting of three notes).  surprisingly, it even
supports chords, dynamics and articulations!

tri =
#(define-music-function
     (parser location noteI noteII noteIII)
     (ly:music? ly:music? ly:music?)
  #{
     \times 2/3 {
        $noteI
        $noteII
        $noteIII
      }
  #})

\relative c'' {
    \key e \major
    \time 3/16
    r16   r   \tri <a cis>32 ( b a
    |
    \tri fis-> dis cis   \tri a fis dis   \tri cis\f dis fis
    |
    \tri a-> cis dis   \tri fis \< a cis   \tri dis fis b\f )
}

Feel free to add it to LSR and anywhere you'd like.
