Cook bacon in a large nonstick skillet over medium-high heat until crisp; remove bacon, reserving drippings in pan. Set bacon aside.

Add butter to drippings in pan. Stir in leeks, potatoes, and carrots over medium heat; cook 6 minutes or until vegetables begin to soften. Stir in mushrooms and garlic, and cook 5 more minutes, stirring occasionally.

Add wine to skillet, and increase heat to medium-high. Bring to a boil; cook 4 minutes. Stir in chicken broth and cream, and bring to a boil. Cook 17 minutes or until mixture is reduced by half.

Whisk together flour and water. Stir into pan, and cook 1 minute or until thickened. Remove pan from heat; stir in bacon, lobster meat, and next 4 ingredients. Divide mixture evenly into 4 (2-cup) ovenproof bowls; cool 10 minutes.

On a lightly floured surface, roll pastry into a 13- x 11-inch rectangle. Cut pastry evenly into 4 rectangles. Carefully fit 1 rectangle over each bowl, and press pastry gently against the rims of the bowls. Brush tops of pastry with egg. Place bowls on a baking sheet.

Bake at 400F for 20 minutes or until pastry is golden. Serve immediately.
