Whisk together the flour, baking soda, and salt in a bowl until thoroughly combined. In a mixing bowl, beat the butter and sugar with an electric mixer until creamy, about 5 minutes, then beat in eggs, one at a time, incorporating each before adding the next. Beat in the lemon juice, lemon zest, and vanilla extract. Gently mix in the flour mixture until just incorporated. Chill the dough about 30 minutes.
Scoop up about 1 1/2 teaspoon of dough per cookie, gently form into a ball, and place the balls onto baking sheets about 2 inches apart.
Bake in the preheated oven until the cookies are set and just beginning to brown at the edges, about 8 minutes; cool on baking sheets for 1 minute before removing to finish cooling on racks.
