One way to portray her is through her dialogue. A thick curvy confident Bella would speak her mind. Instead of being hesitant, she would be direct in her conversations with the other characters. When dealing with Edward's overprotectiveness, she could firmly state her boundaries and desires, like 'I can take care of myself, Edward, and I want to be part of the action.'
Her confidence could also be shown in her physical actions. In a Twilight fanfic, this Bella could be more physically active. Maybe she takes self - defense classes and is able to hold her own in a fight. When the vampires or werewolves are in a scuffle, she doesn't cower but steps up, using her strength (both mental and physical) to contribute to the situation. This would be a departure from the original Bella who often needed to be rescued.
