Well, at least initially, the first thing to do would be elite replacement - you would need to replace all the heads of the culture industry with qualified people drawn from the political vanguard. If no such people exist, then the field in question will have to be closed down for a few years, until qualified people can be trained. If necessary, it can also be acceptable to work with technically talented ex-liberal opportunists, but only if you already have qualified, loyal and intelligent people drawn from the vanguard at the head of the organisations in question - you need these people to impart direction both on their organisation and its products. The important thing is to put people with the correct loyalties and skillset in all the positions that make a difference.

Obviously, a lot will have to do with educating a new generation of specialists with new values and new methods. If there is a sufficient supply of these people, the newly-selected institutional elites will be able to appoint worthy successors when the time comes, and create worthy products alongside their subordinates until then. Direct political control exercised by the government would also be able to introduce corrections where they are necessary.

As to sustaining these structures, some thinkers like Evola believed that aristocracy was one answer, since loyalties, function and purpose are inherited from the parents. Creating a new aristocracy that controls certain functions of the state and society would be one way to introduce long term stability. Another way would be to insitute a system that sorts people according to their personal preferences, loyalties, character and talents - this would allow the state to make use not only of the right people, but also in the right way. Yet another way would be to give a monopoly to all positions of power to elitist political organisations that are open to all but maintain very high requirements for entry and continued participation in every conceivable respect - this would also prevent those who seek profit and the easy life from ending up where they do not belong.

This is just a very brief and general examination of the issue. All of these ideas - and many others that I did not mention - could be developed in a lot more detail. I think the specifics should be figured out according to the situation and the context of the implementation. The main thing, in my opinion, is the size, quality and diversity of the vanguard - if there is a sufficient number of loyal, devoted, united and capable people, skilled in various fields from politics to entertainment, then it will be easy to achieve a smooth and effective transition and consolidation of power. If the number, character, unity or skills of these people prove insufficient, then all sorts of tremendous problems will emerge.
