Preheat the oven to 350 degrees F. Lightly coat a 9 by 13-inch pan with oil and set aside.
In a large bowl, combine the whole wheat and all-purpose flour, baking powder, ginger, cinnamon, baking soda, salt, cloves and 1-1/4 cups of the drained pears. Stir to combine and evenly coat pears with the dry ingredients.
In the bowl of an electric mixer fitted with the paddle attachment, combine the brown and granulated sugar, eggs, and oil. Beat on medium speed until smooth.
Add the dry ingredients to the mixer bowl in 2 additions, alternating with 3/4 cup of the reserved pear juice. Mix the ingredients on low speed until just combined; do not overmix or the cake will be tough.
Remove the bowl from the mixer and use a spatula to fold in the remaining pears by hand. Pour the batter into the prepared pan and use a spatula to evenly distribute and smooth the top.
Bake 35 minutes, or until the cake pulls away from the edges of the pan slightly and springs back when lightly depressed in the center. Cool on a rack.
Prepare the glaze while the cake cools. Combine the confectioners’ sugar and lemon juice in a small bowl and whisk until smooth. Drizzle a tablespoon of lemon glaze over each square.
