One possibility is Regina Coeli... since it is liturgically about to come to an end at this point of Paschaltide. Lots of versions to select from... Cottone, Lotti, Wilkens, chant, etc.. Another might be Iesu Redemptio Nostra, either as a motet (Byrd for example), or as the hymn itself (vesper hymn for the Ascension).
