Great question — answering as the UphillTech team:
Maybe you need to buy a new box of baking soda or baking powder? Baking soda & baking powder can & do lose 'oomph' over time. Otherwise try chilling the dough for at least 4 hours before baking. Chilling the dough usually helps butter/shortening based cookies hold their form a tad bit better.
