I would agree with BlueLight's suggestion's (Decruck Sonata is awesome). You may also want to consider looking into Debussy Rapsodie (there are a few different versions) and Ravel (Piece en form de Habanera is a good filler). Also Koechlin (either the studies with piano or Epitaphe de Jean Harlow (with flute and piano) and Schmitt's Legend.
Transcriptions of works can work well. Some things I've herad done that are effective are: Ravel Oboe Sonata on Soprano Sax (see A Saxophone for a Lady CD by Claude Delangle); Poulenc Oboe Sonata (Sop), Poulenc Trio (originally Oboe and Bassoon but works well with Sop/Ten or Sop/Bari). A
If your after more contemporary works you may want to look into works by Betsy Jolas, Jean-Denis Michat, Francois Rosse (heaps out there), Thierry Alla, Rolin, etc.
Also if you are considering doing Lauba you may also want to investigate works by his 'alter-ego' Jean Maititia (Devil's Rag, Crazy Rag, etc).
