A single member LLC is taxed as a sole proprietorship. For tax purposes you will not see a change in how you report your income on your federal tax return. If your LLC has an EIN you can include the EIN on your Schedule C. You can also include the new name of the business if that also changed.
For state reporting, most states follow the federal guidelines, but not all states do. I would check with your state to determine if they have separate filing requirements for a single member LLC. Generally if they do it is an information return with an annual fee rather than an actual income tax return.
