Converting Trigger to Class

Hey everyone,
I need some help converting my Apex trigger into a class. I am just unsure about the syntax differences between the trigger and class and I'm aware that I can't use trigger.new in the class. Do I need to create a new list to be able to use trigger.new? Any help or direction would be greatly appreciated!

Trigger: 
trigger TotalAumUpdate on Account (after update) {
    for(Account acc : Trigger.new){
        Account oldAcc = Trigger.oldMap.get(acc.Id);
        if(oldAcc.Total_AUM__c != acc.Total_AUM__c){
            List<Opportunity> opps = [SELECT Id, AccountId, Current_Balance__c from Opportunity where AccountId = :acc.Id];                              
            List<Opportunity> newids = new List <Opportunity>();
            	for(Opportunity opp: opps){
                    if(opp.Current_Balance__c != acc.Total_AUM__c){
                        opp.Current_Balance__c = acc.Total_AUM__c;
                        newids.add(opp);
                    }
            }
            if(newids.isEmpty()== false){
                update newids;
            }
        }
    }

}

Hi Damon,

Please check once below code :  
trigger TotalAumUpdate on Account (after update) {
    updateOppAmount.updateAmount(trigger.new,Trigger.oldmap);
}

public class updateOppAmount {
    
    public static void updateAmount(List < Account > accs, Map < id, Account > oldMap) {
        set < id > accIds = new set < id > ();
        
        for (account acc: accs) {
            Account oldAcc = oldMap.get(acc.Id);
            if (oldAcc.Total_AUM__c != acc.Total_AUM__c) {
                accIds.add(acc.Id);
                
            }
        }
        
        
        
        List < Opportunity > opps = [SELECT Id, AccountId, Current_Balance__c from Opportunity where AccountId in : accIds];
        List < Opportunity > newids = new List < Opportunity > ();
        for (Opportunity opp: opps) {
            if (opp.Current_Balance__c != acc.Total_AUM__c) {
                opp.Current_Balance__c = acc.Total_AUM__c;
                newids.add(opp);
            }
        }
        if (newids.isEmpty() == false) {
            update newids;
        }
    }
    
}

Hope this helps you.

you can use trigger.new in the class. when the trigger executes trigger.new get the appropriate values.

Yes that does help me understand it better, you didnt have to code the entire class for me but I'm not going to complain about it. Thank you!
