1) Only landowners can vote.
This would exclude me, currently, but I don’t think anyone who doesn’t own land is qualified to be making decisions that mostly effect those who do. If you own land, you are obviously more established and therefore more effected by the economic decisions made at the government level. This is how it used to be. This would also prevent those who leech government programs from also indirectly controlling those programs.

2) State legislatures elect the President.
This is how it used to be. This prevents “celebrity politics” - in order to get elected, you have to have “street cred” among legislators, not just appeal to the flaky and fickle masses. This is still self-government; the people elect their legislators.

3) All taxes are paid to the states; the states then pay the federal government based upon how many Representatives they have in Congress.
This prevents us for paying for some stupid commune in California, bridge in Alaska or “art” museum in New York. Local governments have FAR more accountability to the people in how they spend money.

4) Uphold the Bill of Rights (example: right to bear arms and provide teeth to the idea that we rule ourselves).
Self-explanatory.

5) No non-elected official can ever create a law or regulation that is legally enforceable. Every law must be passed singly by an elected legislative body.
Self-explanatory. Examples of tyrannical bureaucracies that were created by Congress and then left to its own devices: the EPA, the Department of Homeland Security, the Department of Education, the FCC, etc.

These are just my humble proposals, but think about them.
