As the title says. How could we get a Yugoslavia dominated by Croatia, instead of by Serbia?
Not uniting the State of Slovenes, Croats and Serbs (and rename it Yugoslavia) with Serbia and Montenegro would help. That makes the Croatian portion of the population much higher.
Take a look at the demographics of Yugoslavia in 1918. The Serbs are the biggest percentage (~39%), with Croats second (~24%). Without either Montenegro or the Kingdom of Serbia, Croats make up a much larger percentage.
From there, you need to stack the government of *Yugoslavia with Croats, possibly in coalition with Slovenes - you have a shared religion (Catholicism) to help out there.
IOTL, Yugoslavia was effectively the successor state to the Kingdom of Serbia, so it is hard for it not to be dominated by Serbs.
Simple.
State of SHS is not united with Serbia after WW1. That would require different WW1 post-war situation (stalemate in late 1917, Austria-Hungary still collapse, weaker Italy).
State of SHS was renamed into the Republic of Yugoslavia with its capital in Zagreb. Over time, the state becomes a federal republic. After the war, Serbia unites with Montenegro in the Kingdom of Serbia-Montenegro. Vojvodina remains part of Hungary.

Clever, but I think this is kind of cheating since it isent "Yugoslavia" in the sense of the country we think of. Another easy way to get the whole of historical Yugoslavia to be Croat-dominated might be to extend the length of both WW I and WW II and have AH, Bulgaria, and the Free State adopt stronger Anti-Serb policies that result in land confiscation, interethnic violence, ... Nazi like stuff (nervous cough), with the interwar period also being one of economic downturn. This would not only reduce Serb ethnic percentage, but make Croatia the nation's industrial-economic center.
I really do not see a way for Croatians to dominate in any kind of Yugoslavia that has anything approaching OTL borders. Posters before me have mentioned SHS, but that is not Yugoslavia, not really. Hard truth is that any state that wishes to call itself Yugoslavia has to have both Croatia and Serbia within it, they are the two dominant South Slav peoples, Yugoslavia can exist without Slovenia or Macedonia, but not without Croatia and Serbia forming a part of it.
Of course, we have seen what happens when you bring Croats and Serbs together in a single state. We are our own worst enemies, no outside threat is as dangerous as the forces that existed in both Yugoslavias, Croatian separatism and Serbian nationalism are very powerful and dangerous things, as we have seen these past 80+ years.
On one hand, with a Nazi victory you could plausibly have the Nazis hand over Serbia to their loyal Croatian Utashe puppet. On the other hand, just thinking about what could happen there makes me feel gross and sad inside.
Alternatively, maybe you could get Slovenes and Bosniaks to identify as Croats somehow.
The Croatian lands somehow become far more industrialized durring Austro-Hungarian rule, then it, rather than Slovenia is the centre most developed portion, and unlike the Slovenes the Croats would actually have enough demographic strength to throw their economic weight around.As the title says.
