createRecordInLWC.js

import { LightningElement, track} from 'lwc';

// Importing Apex Class method
import saveAccount from '@salesforce/apex/LWCExampleController.saveAccountRecord';

// importing to show toast notifictions
import {ShowToastEvent} from 'lightning/platformShowToastEvent';

// importing Account fields
import NAME_FIELD from '@salesforce/schema/Account.Name';
import Phone_FIELD from '@salesforce/schema/Account.Phone';
import Industry_FIELD from '@salesforce/schema/Account.Industry';
import Type_FIELD from '@salesforce/schema/Account.Type';

export default class CreateRecordInLWC extends LightningElement {
    @track error;

    // this object have record information
    @track accRecord = {
        Name : NAME_FIELD,
        Industry : Industry_FIELD,
        Phone : Phone_FIELD,
        Type : Type_FIELD
    };


    handleNameChange(event) {
        this.accRecord.Name = event.target.value;
        window.console.log('Name ==> '+this.accRecord.Name);
    }

    handlePhoneChange(event) {
        this.accRecord.Phone = event.target.value;
        window.console.log('Phone ==> '+this.accRecord.Phone);

        window.console.log('Industry ==> '+this.accRecord.Industry);
    }


    handleSave() {
        saveAccount({objAcc: this.accRecord})
        .then(result => {
            // Clear the user enter values
            this.accRecord = {};

            window.console.log('result ===> '+result);
            // Show success messsage
            this.dispatchEvent(new ShowToastEvent({
                title: 'Success!!',
                message: 'Account Created Successfully!!',
                variant: 'success'
            }),);
        })
        .catch(error => {
            this.error = error.message;
        });
    }
}

Apex Class

public inherited sharing class LWCExampleController {

    @AuraEnabled
    public static void saveAccountRecord(Account objAcc){
        try{
            insert objAcc;
        }
        catch(Exception ex) {
            throw new AuraHandledException(ex.getMessage());
        }
    }
}

Result
