Preheat oven to 350F. Lightly butter the base and sides of a 9x13 dish.
To prepare streusel:
Whisk together dry ingredients, and then using hands work in softened butter until it resembles a coarse crumble.
To prepare coffeecake: Cream together butter and sugar until light and fluffy. Add eggs, individually, scrapping down sides as needed. Add lemon zest, buttermilk and vanilla.
In a separate bowl, whisk together flour, baking powder, baking soda and salt.
By hand, slowly fold dry ingredients into wet, being careful to not over-mix. Batter will be lumpy, that's okay! Gently fold in strawberries, and then pour batter into prepared pan and spread evenly. Top with streusel.
Bake for 45 minutes, and then check cake by inserting a toothpick into the center once the top no longer appears "wet". Continue baking if needed until top is golden and center is set.
To prepare glaze:
Mix almond milk and lemon juice, and then whisk in powdered sugar until thick consistency is achieved.
Drizzle glaze over top once the cake is completely cooled.
