According to KDE-Akademy "Call for papers"  ,  i have to send an e-mail at email@example.com before 18/04 in which i include a brief summary of the presentation. At 23/04 the accepted presentations will be announced. So i follow the steps ;)
Furthermore i will have a look at our repo  and Talking Points  as well. Combing stuff from artwork, my points of view , talking points and other past presentations would be a good choice i think . Also i hope that the presentation will be accepted and i will order material and stuff from .
