Luchi is a Bengali puffed deep-fried bread made using maida (all-purpose flour), while Puri is North Indian puffed bread made using whole wheat flour (atta). Luchi is lightly fried and almost without brown spots, while normal poori is fried until slightly browned. Phulko luchi is much softer than poori since it is made using maida, and some oil is added to the dough.
