I would suggest following a Domain Driven Design (DDD) and one suggested way of laying this out would be creating the following projects:

Company.Project.Web <-- Your MVC Application, though you can still use WebForms Company.Project.Domain <-- Data Transfer Objects (DTO's), ViewModels, Business Logic, Events Company.Project.Data <-- Repository Interfaces

Company.Project.Data.EF <-- EntityFramework Specific Implementation of Repositories Company.Project.Model <-- Your EF CodeFirst Classes

Company.Common <-- A common project of utilities and/or extensions
